A blood flow environment simulation device, comprising: a liquid reservoir (1) for storing a liquid; a blood vessel simulation tube (4); a pump (2) for pumping the liquid; several circulation tubes (7, 11, 12), together with the blood vessel simulation tube (4), forming a circulation path for the liquid; and a valve (6) located in the circulation path, having a valve inlet (17) and a valve outlet (18), the area of the valve inlet (17) being variable, so as to change the kinetic parameters of the fluid within the blood vessel simulation tube (4) over time. A medical apparatus comprising the blood flow environment simulation device.
